(Cl. 222-131) The present invention relates to portable beverage dispenser and more particularly to an insulated beverage dispenser to be supported upon the shoulder and back of a vendor or the like.

At the present time many stadia, baseball parks and the like prohibit the sale of bottled beverages to the spectators in the stands; at best, such bottled beverages are often sold at certain designated locations, usually underneath the stands and relatively distant from a spectators seat.

The subject invention relates to a light weight, insulated dispenser supported upon the back and shoulders of a vendor whereby the said vendor may travel throughout the stands and dispense beverages to a spectator in his seat, with no appreciable temperature change in the beverage between first and last servings. Additionally a modification of the invention permits the vendor to serve heated beverages with complete safety to both vendor and spectator.

An object of the present invention is the provision of a light weight, insulated, beverage dispenser suitable for use with either hot or cold beverages wherein the vendor is free to move throughout the stands and dispense the said beverages to the spectators in their seats.

Another object of the invention is to provide a light Weight dispenser including all necessary equipment and supplies whereby a vendor may remain in the stands for extended periods of time to serve beverages to spectators.

A further object is to provide a dispenser which weighs less than thirty-six pounds when fully loaded with 2% gallons of beverage and cups.

A final object of the present invention is the provision of a beverage dispenser which is simple in construction, capable of mass production techniques, easy to service and store, capable of being maintained in a sanitary condition, and is universal in its adaptability.

Referring now to the drawings wherein like reference characters designate like or corresponding parts throughout the several views, there is show-n in FIGS. 1-8 of the drawings a preferred embodiment of the portable beverage dispenser 20 of the subject invention, which dispenser is to be supported upon the shouldersand back of a vendor.

More particularly, dispenser 20 consists, in part, of a casing 21 which is preferably of integral construction and molded of high impact plastic or Fiberglas, or alternatively, pressed of a light weight metal such as aluminum. As best seen in FIG. 2 of the drawings, casing 21 consists of front 22, sides 23-24, V-shaped back 25,

top 26 and bottom 27. A shaped lid 28, composed of the same material as the casing, includes a downwardly depending flange 29 which overlaps the uppermost marginal portions of the casing 21 in tight fitting relationship.

Top 26 includes a large, centrally positioned bore defining a longitudinally extending cylindrical chamber 30 which is defined (see FIG. 1) by side wall 33 and base 34 and laterally rearward, transversely aligned bores 31- 32 of lesser diameter than the bore of chamber 30. A vertically aligned cylinder 35 includes an integrally formed base 36 which terminates slightly above the base of cylinder 33; cylinder 35 opens upwardly and the rim is secured in bore 31. As viewed in FIG. 8 of the drawings, a bore 37 is provided in the bottom 27 of the casing; each end of a cylindrical tube 38 inserts into and is secured in bores 32, 37 respectively, the purpose of which will hereinafter be discussed in connection with FIG. 8 of the drawings. A work hole, not shown, is provided in the casing thus formed and the interior of the casing fil'led with an insulating material 39 such as styrofoam, polyfoam, polystyrene or other expandable foam, and the work hole sealed in a convention-a1 manner.

To conserve storage space when the dispenser is not in use, straps 40-41 are detachably secured to the upper, lateral portions of the back of the casing. For purposes of convenience only, strap 40 will be described in detail, it is to be understood that strap 41 is constructed in like manner. Referring now to FIGS. 1, 3 and 4 of the drawings, an elongated plate 42 includes integrally formed, 'trian-gularly positioned, outwardly extending pins 43 which terminate in buttons 44 or the like. Countersunk bores 45 are provided in plates 42, bolts 46 pass through the bores 45 and thence through aligned bores 4748 in the casing and backing plate 49, respectively, and nuts 50 threaded thereon.

The straps 40, 41 are constructed of flat spring steel or the like, and are essentially inverted U-shaped in elevation. The lower, rear portion of each strap is turned angular-1y outward and then vertically downward, indicated by reference numerals 5152, respectively. As illustrated in FIG. 3, portion 52 is provided with a plurality of bores 53 which are slightly greater in diameter than buttons 44 and aligned with respect thereto to receive the same; each bore includes a downwardly extending elongated slot 54. Buttons 44 insert into the corresponding bores 53 and as the straps 40, 41 are raised, the pins 43 slidably insert into the respective slots 54 until stopped by bearing against the lower ends thereof. It is obvious that each. strap may be removed from the casing. simply by reversing the aforementioned steps.

A cushion =55, composed of foam rubber or the like, is secured to the undersurface of each strap by means of a suitable adhesive. The lower front end 56 of each strap, as view in FIG. 5, terminates at an angle of approximately forty-five degrees with respect to the longitudinal axis of the strap facing outwardly. An elongated slot 57, the longitudinal axis of which is parallel to end 56, is provided in proximity thereto to receive the mating element on the harness, hereinafter to be described.

In FIG. 1 there is shown a bracket 58 which is secured to the lower rear corner of each side 23, 24; the longitudinal axis of said bracket extends angularly upward at-an 'angle of approximately [forty five degrees.

More specifically, bracket 58 includes a reduced base 59 through which rivets 60 or other fastening means pass to secure the said bracket to the respective side of the casing. The bracket '58 further includes an intermediate, outturned portion 61 and terminates in portion 62, the longitudinal axis of which parallels the corresponding axis of base 59. An elongated, transverse slot '63 is provided in portion 62 adjacent the upper end of said bracket.

Referring again to FIG. 1 of the drawings, a web or the like is passed through slot 63 and secured'in such position by means of rivets 64 or the like, forming portions 65-66 of the belt and harness. A buckle 67, of conventional design, is secured to the free end of portion 65; the corresponding portion 68 secured to the opposite side of the casing remains free to insert into the buckle 67. The belt thus (formed passes around the waist of the vendor and prevents the dispenser from rocking to-and-fro and sideways as the vendor Walks.

The harness is formed by portion 66 which extends upwardly along the rib cage of the vendor :and the end thereof secured to hooking device 69. More specifically, hooking device 69, as best seen in FIG. 5, includes a flat base 70 with a transverse, elongated slot 71 therein; the free end of portion 66 is looped through said slot and secured in a conventional manner. A reduced portion 72 of said hoolcing device is bent upwardly and rearwardly to form a hook 73 which inserts from underneath into the slot 57 provided on the front end of each strap 40, 41. The harness secured to the opposite side of the casing and strap, respectively, is constructed in like manner.

As shown in FIG. 1 of the drawings, an inverted J- shaped tube 74 is secured to the left hand strap along the upper surface thereof. As will hereinafter 'be more fully described in connection with FIG. 6, a valve '75, suitable for dispensing beverages and the like, is secured to the lower end of tube 74. A flexible hose 76 passes through tube 74 and one end thereof connects to valve 75. A recess 77 is provided in the flange of the lid 28, and the hose passes therethrough and the other end thereof detachably connects to container 78 in a manner hereinafter to be described in detail.

Referring now .to FIGS. 2 and 8 of the drawings, there is shown a cup dispenser 79 which is secured in the lower portion of tube 38. The said cup dispenser consists of a cylinder 80 which terminates downwardly in an outturned flange 81; the cylinder 80 is inserted upwardly into tube 38 until stopped by flange 8'1 abutting the bottom 27 of the casing and is secured in such position by means of an adhesive 82 such as epoxy or the like. A plurality of opposing fingers 83, composed of spring steel or the like, are secured as by rivets 84 to the inner surface 'of cylinder 80; each of said fingers includes a :downwardly inclined Referring now to FIGS. 2 and 7 ofthe drawings, container 78 inserts into cylindrical chamber 30 and is sup.

ported by the base 34 thereof; the said container is coni structed of stainless steel or the like, is of 2 /2 gallon capacity and is manufactured for applicant by the Firestone Steel Products Company, a division of Firestone Tire and Rubber Company of Akron, Ohio.

A centrally positioned opening 88, oval in plan, is provided in the top 89 of said container, and a lid 90 15 which carries a rubber gasket .91 inserts therein. A locking mechanism, indicated generally at 92, pivotally connects to the lid 90 and bears against the top 89 of said container. When the locking mechanism is pivoted to the limit of action in one direction, the lid 90 may be :re-. 6

moved by rotating the same transverse to the opening 88 and withdrawing the same upwardly throughthe opening. When the lid is properly positioned and the locking mechanism is pivoted to the limit ofits action in the opposite direction, however, the lid is forced upwardly by the wedging action of such mechanism against the container top; gasket 91, carried by the lid, bears against the under surface of top 89, sealing the lid to the container.

As shown in FIG. 2, a pressurized 'bottle 93 of carbon dioxide gas inserts into cylinder 35 and connects to container 78. Such bottles normally include a cutoff valve 94 and a female threaded portion into which a nipple 95 or the like inserts and to which is connected a pressure regulator 96. It is to be understood that said pressure regulator may be of the type which provides a set, predetermined pressure, preferably of 14 psi. operating line pressure, or alternatively, of the type wherein the said pressure may be manually adjusted to provide such desired line pressure. One end of hose 97 is secured to said pressure regulator by means of pipe band98- or the like; the other end of said hose connects and is, secured bypipe band 99 to a quick disconnect in coni nector 100 such as is manufactured by the Cornelius Company of Minneapolis, Minnesota. Connector 100 detachably connects to a mating plug 101 (see FIG. 7) which includes a plunger type pressure valve (not shown). The plug 101 screws onto fitting 102 secured to the ,top 891 a plunger type pressure valve screws onto fitting 107 and 1 a mating, quick disconnect out connector 110 manufactured by the Cornelius Company attaches thereto.

Hose 76, heretofore mentioned, is secured to connector 110 by means of a pipe band 111 or the like.

When the cut-01f valve 94 of the bottle of carbon dioxide gas is opened, gas at the desired pressure is sup-' plied to the sealed container 78, the beverage therein is charged and is dispensed by activation of valve 75 into the cups provided by the cup dispenser 79.

There is shown in FIGS. 9-13 of the drawings a portable dispenser 117 designed for use in connection with dispensing heated beverages and liquids, wherein a source of pressurized gas it not utilized. Since the said dispenser is similar in many respects to the preferred embodiment of FIGS. 1-8, corresponding parts will be designated by the reference numerals heretofore given for such parts in the preferred embodiment. In such modification, since a bottle of pressurized gas is not utilized, the cylinder 35 is dispensed with and a circular plate 118 secured in bore 31 to plug the same. Furthermore, a bore 119 is provided in the center of base 34 and a vertically aligned bore 120 provided in the base 27. A vertically extending tube 121 is secured in the bores 119, 120 respectively, the purpose of which will hereinafter 'be described.

In such emodiment of the invention, as illustrated in FIGS. 9 and 10, .a plurality of spaced, adjustable feet, indicated generally at 122, are secured to the bottom 27 of the casing. Each foot includes a screw 123 which inserts into a bushing 124 secured to the bottom 27 in a conventional manner. Screw 123 terminates downwardly in a button 125 or the like; a jam-b nut 126 threads onto the screw and is adjusted to bear against the lower surface of bushing 124.

Referring now to FIG. 11 of the drawings, container 127 is similar to the container 78 of FIG. 7 with minor modifications. A fitting 128 is secured to the bottom of said container and communicates with the interior thereof. Nipple 129 extends upwardly through the tube 121 and screws into fitting 128. An elbow 130 screws onto the other end of the nipple and a hose 131 suitable for carrying heated liquids is secured thereto as by means of a pipe band 132 or the like. As viewed in FIG. 9, hose 131 is secured to a thumb activated valve 132 such as is manufactured by Reid Valve of Los Angles, California, by means of pipe band 133. When not in use, valve 132 is detachably secured in holder 134 secured to strap 40. More specifically, as shown in FIGS. 9 and 13 of the drawings, holder 134 consists of a base 135, V- shaped legs 136-137 and perpendicularly upstanding spaced prongs 138-139. Base 135 is secured to strap 40 adjacent the edge thereof as by rivets 140 or the like. An outwardly opening slot 141 is provided in base 137 intermediate the prongs 138, 139 wherein the valve 132 inserts and is secured.

The fittings 102, 107 and plugs 101, 109 utilized in connection with such embodiment are similar in construction with FIG. 7 of the drawings except that the plunger type, pressure valves incorporated in the said plugs 101, 109 are removed to provide an air vent for the said container. Additionally, an adjustable vent 142 of conventional design is provided on the lid so that additional air may be admitted into the container 127.
